BED-FURNACE.

SPECIFICATION forming part of Letters Patent No. 404,280, dated May 28, 1889.

Application tiled August 25, 1888. Serial No. 288,752. (No model.)

To all whom, t may con/corn:

Be it known that I, ELWOOD E. I-IIATT, a citizen of the United States, and a resident of Noblesville, in the county of Hamilton and State of Indiana, have invented certain new and useful Improvements in Bed-Furnaces; an d I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or ligures of reference marked thereon, which form a partof this specification.

Figure l of the drawings isa representation of this invention and is a vertical section through the center. Fig. 2 is a front view, partly broken away and partly in section. Fig. 3 is a horizontal section taken where the broken line .fr is marked on Fig. l. Fig. 4 is a det-ail.

The invention relates to improvements in bed-heating furnaces; and it consists in the construction and novel combination of parts, as hereinafter set forth.

In the drawings, A designates a vertical wall, which may be of wood, preferably having the rounded upper corners, as shown. The said wall is held in a vertical position by means of the front plinth, B, and the rear plinth, C, which are bolted or otherwise secured thereto at cach side of the lower edge portion of the wall. The `interior surface of the vertical wall Aris designed to be covered smoothly with tin or other metallic plate, as shown at D, and a front wall, E, of Inetal, is rigidly secured to the edge of the wall A and to the front plinth, so that a hot-air chamber, F, is formed between the walls.

G is a radiator-plate secured at one edge to the wall A and curved over the heat-inlet pipe H within the chamber F. Thisv plate is designed to distribute the heat to all portions of .the chamber F, and small holes a are provided in the top of the plate, through which the heated air may pass upwardly. The heat-inlet pipe l-I extends through an opening in the plinth B and has a bell-mouthed lower end, b, under which it is designed to placea lampflame. It is obvious that this pipe I-I maybe of different shape and length from that shown, and it may be so placed as to receive heat from a gas-burner.

I is the Ventilator or escape-tube seated in the longitudinal groove or slot c in the wall A between the plinths. The said tube is provided centrally with a short outlet-tube, d, which extends through an opening in the plinth C, and at each end the said tube communicates with the chamber F by means of the elbow-joints e, seated in the plint-h B. The outer portion of the pipe Il is preferably incased with some incombustible material to prevent the heat from injuring the clothing of the bed, and I prefer, also, to cover the whole furnace with felt or other soft material.

It is evident that the furnace maybe made 'in any desired form or dimensions. i

I-Iaving described my invention, what I ELWOOD E. I'llAT'l.
